That works only if you can avoid the terrorism. I happened to be scheduled to fly from Frankfurt to Detroit that day. I had spent over two weeks in Germany on a business trip, and could have had an all expenses paid two day "vacation" there if I stayed until Sunday. At the last minute I changed my flight to Friday, in order to get some rest.
I may have been on that flight. At the time , there were only three airlines with Frankfurt to Detroit flights, Lufthansa, British Air, and Pan Am. The tickets were interchangeable, and I always chose one of the three at the last minute, depending on when I got to the airport.
Wow glad you missed it
